Exercise Science Fun Facts🤓

1️⃣ At sea level and on a mountain there is exactly 20.93% oxygen in the air. So the air isn’t “thinner” but you can’t deliver oxygen to the muscles as well due to less hemoglobin binding. (Note: Technically as pressure drops from ~760mmHG at sea level to ~253-500mmHG at the peak of a mountain oxygen molecules are more spread out so it’s a combination of pressure change and oxygen delivery contribute. I have a full explanation on YouTube)

2️⃣ On average men sweat more than women. This is because women take better advantage of convection cooling, which can be an advantage in long competitions where hydration is a big factor.

3️⃣ Quickly hyperventilating for a few seconds before holding your breathe can decrease partial pressure of CO2 and help you hold your breathe longer.

4️⃣ During long endurance events, as you sweat you lose blood plasma volume leading to an increase in heart rate known as cardiac drift.

5️⃣ Your lungs don’t burn when you run in the cold, it’s actually your trachea hydrating the air.
